Explanation
Kangaroo rats are a classic textbook example of animals that survive without drinking water because they feed on carbohydrate-rich seeds, whose metabolism generates sufficient 'metabolic water' to meet their physiological needs — a different mechanism from anhydrobiosis, which involves entering a dormant, desiccated state (as in tardigrades), not applicable to metabolically active kangaroo rats.
